ASTM D1822 is a standard published by the American Society for Testing and Materials (ASTM) titled “Standard Test Method for Tensile-Impact Energy to Break Plastics and Electrical Insulating Materials.” This standard provides guidelines for determining the tensile-impact energy required to fracture plastics and electrical insulating materials.

ASTM D1822 test method involves subjecting a notched test specimen to combined tensile and impact load until a fracture occurs. The energy required to break the specimen is measured, providing valuable information about the material’s ability to withstand both tensile and impact forces.

This standard establishes specific procedures for specimen preparation, test conditions, and results calculation and reporting. By following this standard, consistent and reliable testing can be achieved, allowing for meaningful comparisons of different materials.

Class J – Charpy and Izod Automatic Impact Testing System complies with ASTM D1822 standard.
